About this video
The addresses in this video are examples.
Video transcript
To check an email address, go in order: format, then domain and MX, then the mailbox. Format goes first. It catches a missing domain, a doubled dot, or a space pasted in from a spreadsheet. Next, the domain and its MX records. Plenty of real domains run a website but never take mail. Only then is the mailbox tested. The receiving server is asked about this one recipient, and nothing is delivered. The order tells you what broke. A domain failure means the whole address is wrong. A mailbox failure means this person isn't there. Check one address free at billionverify.com.
